A method of experimental determination of components evaporation rate from a sulfuric acid solution during its concentrating in the flow of neutral gas is proposed. Using this methodology, the dependence of the evaporation rate on the composition of the acid solution is set. The critical value of the weight fraction of water in the solution was found at which the character of this dependence changed. An empirical equation for the approximate calculation of the evaporation rate of components from solution in the air flow was obtained.
